SPECIFICATION forming part of Letters Patent No. 685,420, dated October29, 1901.

Application filed December 17, 1900- Serial No. 40,108. (Mod'eL) To ctZZwhom it may concern.-

Be it known that I, GEORGE GOODLINE, a citizen of the United States,residing in Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in MechanicalMovements; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

This invention relates to mechanical movements; and the object of theinvention is to provide a certain combination of parts of- Where it isnecessary that a reciprocating part should be intermittently maintainedat a dwell, especially if simplicity is a characteristic feature of themechanism from which such movement is derived and the parts aresusceptible of being constructed with a View to durability and foralterations, so that variations in the relative extent of theresultantreciprocation or dwell can be obtained.

As illustrating particularly one adaptation of my invention reference ismade to its application as an actuating mechanism for the boxstructureof a loom, this being an excellent example of an intermittently-movablepart, which circumstances require should be held positively stationarybetween its actuations.

The invention is fully illustrated in the accompanying drawings, whereinFigures 1 and 2 are side views of one form of the mechanism whereby Iobtain the movement above referred to, the arrangements of the parts inthe two figures being such that said parts are ready on the one hand forthe movement of the oscillatory part in one direction and on the otherhand for the movement of said oscillatory part in the other direction.Figs. 3, t, and 5 illustrate the rela tive disposition of the parts atseveral points during the movement of the oscillatory part in onedirection. Fig. 6 illustrates the relative disposition of theparts atthe inception of a dwell in the action of said oscillatory part. Figs.7- and' 8 illustrate the relative disposition of the parts at two pointsduring the movement of the oscillatory part in the other direction.Figs. 9 and 10 illustrate modified forms of said mechanism, and Fig.

Said rotary part has a shaft or axis 0, which is journaled in a frame(Z, and it is provided with a crank 6, attached to said shaft, wherebysaid rotary part is driven. H

f is the element to which the desired alternating reciprocation anddwell movements are to be imparted, and g is the support in which saidelement slides.

72 designates a pin pivotally connecting the part b and the element f.The free end portions of the part b and the part a are disposed side byside, and the range of movement of the former is approximately equal tothe diameter of the latter.

011 the face of one of the two parts Ct 11 which is adjacent the other'Iprovide a pin '5, and in the other part1 provide two sockets or recessesj, which open in opposite directions,

extending substantially in a line drawn at pin '5 be mounted, as shown,on the part a,

while the two sockets are formed the one in the upper edge and the otherin the lower edge of part I). Now upon rotating the part a, it beingassumed that no external force,

such as the action of gravity, is operating on part b, the latter willbe engaged by the pin 7;, which will first move into the adjacentrecess, pushing the free end of part 1) before it and imparting to itits own rotary motion until they together reach such a position thatwith the continued movement of the pin said pin can clear the recess andfinish its circle of movement idle. Thereupon said pin will continue ontill it again enters the other recess, and, as before, will drive thepart b before it until the latter reachesa position diametricallyopposite its last stopping-point, when the pin will clear this recessalso, passing on idle till the original recess is again entered. In thisway alternate reciprocations and dwells can be effected in the part b.\Vhere one pin is provided, the part a makes one and one-halfrevolutions to each movement of the part b. )Vhere, as preferred and asillustrated in the drawings, two pins are provided, being diametricallydisposed, part Z) makes one movement to each full revolution of part a,the operation being otherwise similarto that where one pin is used. Ofcourse in order that the pin or pins may clear the part I) as they passthe same it is necessary that at the point where they proximate it, atleast, it should be formed to offer no obstruction. Fig. 10 shows themain portion of said part offset as regards the free end portionthereof,so as to afford the necessary clearance.

The mechanism so far described is capable of producing merely thedesired alternate reciprocation and dwell movement in a given part andis without means, after the pin that has just acted leaves one of thesockets, for maintaining such part positively stationary during thedwell. Such means I will now describe.

To the end in view I preferably provide the part Z), which is in effecta connectingrod, with a head k,having four pins Land constituting what Iterm a claw. It is this part which is provided with the sockets orrecessesj. These pins, which project toward the part a, are arranged inpairs, one above and one below the longitudinal axis of the red I). Thepins in one pair are equidistant from the rotating center for the pinst'in the adjacent socket j, while the pins in the other pair areequidistant from the corresponding point in the other socketj. On theface of the disk or other device forming the part a, which adjoins therod Z), two diametricallydisposed channels m are formed, these channelsbeing adapted for the reception of the pins Z. The pins in each pair(provided it is the sooketj corresponding thereto which is at the timeholding one of the pins t' and provided this pin is acting to drive therod 1) from the one to the other of its limits of movement) are adaptedto: follow each other through the channel as the disk makes ahalfrevolution, (see the arrows in Figs. 1, 2, 3, 5, and 7,) and forthis reason the said channels have a circular or part-circular form,

being described about the pins 2 and having radii of coincident lengthwith the distance between each pin Z and its corresponding socketj. Inthe said face of the disk I also out a circular channel 02, whichintersects the other two and has its center coincident with the centerof rotation of said disk. In this channel while the rod is at dwell andwaiting for the approaching pin the innermost pins i. c., the innermostone in each pair-have free way, the one after. the other, while the diskcompletes its half-revolution unimpeded. (See the arrows in Figs. 6 and8.) Said channel, therefore, in the interval when the pins 1' are clearof the sockets or recesses j coacts with the pins Z to prevent anylongitudinal movement of the red I). To prevent movement of said rod inany direction during this time, concentric guards 0, which are arrangedto project from those portions of the face of the disk which are insideof and immediately adjacent the circular channel a and between itsintersections with the channel 172, are provided. \Vhile these guardsproject out clear of the general surface of the disk, they do not extendso far, of course, but that the body portion of the rod will alwaysclear them as they pass. The ends of the claw are cut out, so as toproduce recesses 19, which are so formed as to have substantially theshape of the guards, which are thus adapted to exactly fit therein.These guards preventperfectly any movement of the claw in a directiontoward the center of the disk, and since they exactly fit the recessesformed in the ends of the claw they insure against any movement of thelatter in a direction transverse to the longitudinal axis of the red 1).Moreover, it suitable stops are provided, such as the uprights q of thesupport g, against which the pins it take such stops will keep the clawagainst the guards and will coact with the latter to obviate themovement of the red I) in either direction longitudinally when at itslimits of motion.

Owing to the fact that the centers in the sockets or recesses j oftheclaw for the two pairs of pins are not coincident, one pair of saidpins is farther away from each center than the other, and so it becomesnecessary to widen each channel 17? outwardly from its center and fromthe intersection of the three channels to the periphery of the disk, asat r, so that after the disk completes its idle semirevolution (thechannel at having been in use) the pins Z of the pair now about to beidle-2'. a, thrown out of a channel m-can move the one out of and theother into said channel m during, respectively, the beginning and endingof the consequent stroke of the rod Z).

The fact that the centers for the two pairs of pinsl in the sockets orrecessesj of the claw are not coincident, and the consequent fact thateach pin in each pair is farther from the center for the other pair ofpins than the latter themselves are, is advantageous in that IIO I go

but if the parts must, in the use to which they are put, standvertically, as in Figs. 1, 2, 9, and 10, there need be no interferenceor clogging in their action if a reasonable amount of care is observedin cutting the grooves and otherwise forming the mechanismproportionately throughout. For instance, though, when one of the pins1' has carried the rod b to the position shown in Fig. 8 the tendency ofthe rod I) under the action of gravity is to fall, so that the upperinnermost pin Z might as likely drop into channel m as channel a, and soclog the movement. If the widened portions of the channel on have onlythe necessary and no greater width, the corresponding lower pin willtake against the side of the widened portion of the channel which it isentering, as at t, and so sustain the claw and properly guide the saidupper pin.

In order to insure the pins 1' leaving the sockets with clearance, theinner portion of each of them may be trimmed off. I prefer this tocutting away the corners at the mouth of each socket, since thereby theperfect engagement of the pins in the socket is preserved.

I do not wish to be limited to the use of two or any number, in fact, ofthe channels m. For instance, but one need be provided, though in thiscase there must be but one pin 2', and this one must be at its center.Whatever the number of channels at there should be corresponding pins 1'therefor. Moreover, I do not Wish to be limited to the combination ofthe means whereby I effect the reciprocations of the element f with themeans whereby I effect the locking of said elementf between itsactuations, for each is susceptible of use independently of the other,and I therefore.

claim them independently.

Fig 9 illustrates a mechanism whereby the action of the claw istransmitted to the element to be reciprocated directly instead ofthrough the medium of a pivoted connection, such as the body portion ofthe rod 1), of which it forms a part in the other embodi ment of myinvention. In this modification the claw is guided in the element f formovement transversely to the direction of movement of said element,preferably by providing the latter with a slotu, in which a suitableprojection 12 on the claw is guided.

In Fig. 9 the disk is shown enlarged, so as to illustrate that thechannels on may be extended, if desired, to complete the circular form.

In the modification presented in Fig. 10 a disk having several of thechannels m and corresponding pins 2' is shown. The princi- 'ple ofoperation of this disk is practically identical with that which I havealready described, so that it is unnecessary to recur to it. A slightmodification, applicable, in fact, whether the disk has one, two, orseveral channels, is also illustrated in this figure. It will beobserved that the outer margins of those portions of the disk which areoutside the channel n and which stand in relative relief present agenerally circular outline and that the latter is spaced from thechannel a distance corresponding to the spaces between the pins in eachpair of pins Z. Thus while the pins i are free of the recesses and. arerevolving idle the two outermost pinsbe made use of in substitution forthe guards 0.

portion of the disk or by forming a special channel w, such as is shownin Fig. 9.

Any suitable means may of course be provided for keeping the clawsagainst the disk.

I wish it to be understood that the disk is susceptible of being rotatedin either direc tion indiscriminately, only one direction being shown bythe arrows in order to avoid confusion.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-- 1. Thecombination of a rotary part and an oscillatory part arranged side byside, one of said parts having sockets or recesses which openoppositely, each substantially in adirection transverse to the line inwhich the positions of limits of motion of said oscillatory part arelocated, and said sockets being, as to such arrangement, substantiallyconstant, and the other part being adapted to engage said first-namedpart firstin one recess and then in the other, as the rotarypartrotates, to move the oscillatory part alternately to positionssubstantially diametrically opposite with reference to said rotary part,substantially as described.
